To CLZZ whom it may concern:

Be it known that I, ALBERT EniEnLnY, a cltizen of the United States, residing at Chica 'o, in the county of Cook and State of Illi- 1101s, have invented new and useful Im rovements in Metal Shingles, of which the iollowing is a specification, reference being had to the accompanying drawings, forming apart thereof.

The purpose of this invention is to provide an improved construction of metal shingle i'orthe purpose of more secure hastening o] the overlapping elements without liability or with diminished liability ofleakagc byreason of the enetra tion of the metal by the securing-nai s.

It consists of the features of caynstruction set out in the claims.

In the drawings, Figure 1 is a plan view of a portion'oi a roof constructed with this iinproved shingle. Fig. 2 is a section at the line 2 2 on Fig. 1. I Fig. 3 is a detail section at the line 3 3 on Fig. 1.

The shingle A shown in the drawings, made of sheet metal struck up in the die to give the configuration shown and to be. described, is formed with upraised panels 1. in rows, the panels of each row being separated from each other by depressions :2 and being offset half their width from the panels of the next rows, so that the channels 2 of one row start from the middle point of the lower edge of the panels 1 of the row abov The panels are struck up from the plane surface of the metal sheet, so as to slope from the upper edge, where they commence without any upraise to the lower edge, at which the upraise is maximum and presents adownwa1*dly-iacing but somewhat oblique shoulder 3. The channels 2 necessarily have the same raduation of depth from upper to lower ou as the panels. The panels 1 are preferably formed with truncated corners at their lower ends, the shoulders 4 of? :aid truncated corners being preferably at an angle forty-five degrees to the shoulders 3, 0, that the proximate shoulders {i 4: of two adjgcent panels stand at an angle of ninety degrees to each other, defining a right-angular extension 5 at the middie of theupper end of each panel reachingv in between the twoadjacent panels of the row above and merging at its right angle in,

channel 2 between said two the bottom of the At the center or this rightadjacent panels.

angular extension there is formed an annular boss 6, the purpose of which is to seat a lead securing the shingle to the roof. gasket, it will be understood, has the function of securely packing the aperture which the nail makes in perforating the shingle and of packing the head of the nail. In the use of my improved shingle it may not in all cases be necessary to employ the nails 8 in the manner or position shown, and to limit that or any reason would require packing and to secure theshinglc by means which shall tend to prevent the nails which may be employed in the position indicated fromworking out or being drawn out or loosened by the springing or buckling of the metal, which is traction in changes of temperature or from any vibration or springing of the roof as a whole, i provide sheet-metal cleats or retainers 9. These cleats or retainers consist each of a strip of sheet metal shaped to seat on the shingle at the channel 2 and the right-angular panel extension 5, being fitted to the 'up per surface of the panel at that part, and be ing vfrom two to three inches in width, so as to extend an inch or more on each side of the channel 2 when lodged in place upon the shingle. They are intended to be thus lodged only upon the upper row of half-panels of each'shingle, such half-panels being designed for overlapping by the next shingle above. T he shingle is secured to the roof by nails 12, driven through the cleats at opposite sides of the channels 2, and these nails and the ape-r tures which they cause are completely covered by the overlapping of the next shingle. The cleats or retainers are of such length'as these half-panels and. project from under the lower edge of the overlapping shingle, and such projectin end portion 9 of the cleat or retaineris folded back, clasping said lower edge, ontd which it may be tightly clenched its stillness from the point at which the last nails covered by the overlapping shingle are driven down to said fold it may serve to hold the overlapping shingle snugly in position as if such overlapping shingle were nailed along the edge, at which the refolded lip 9* of the gasket through which a nail 8 is driven for The lead;

the necessity for such nails or for any nails whose heads will be exposed and which for liable to occur through expansion and con to extend down past the lower shoulder 23 of down'by hammering at the fold, so that by 7 grasp and 5 point, which would tend,if it shou (1 occur, to

draw out the nail 8. p v

This shingle is formed at the lateral edges with the \I-shaped ribs 10, each adapted to receive or be received by the corresponding rib of the shingle next below it and next adj acent to it. At suitable intervals in the length of the \l-shapedribs at one side there are formed cylindrical bosses 11, sunken at the top, making them annular, the sunken pocket thus formed being designed to receive a lead gasket through which the nail 12 may be driven to secure the shingle along the'rib to the roof. The rib at the other lateral edge may be provided at corresponding positions with cylindrical bosses 13 enough smaller than the bosses 11 to seat Within the latter bosses of the adjacent shingle and enough shorter to accommodate the sunken gasketpocket 11 of the larger boss, such bosses 13 being thereby not quite so high as the ribs in which they are formed; Thepurpose of this construction is to aiford opportunity for effectively packing the securing-nails 12.

I claim- 1. In a metal roof comprising metal shingles successively overlapped, such shingles being struck up 'to forinpanels inrows, the 1 lower row of panels of each shingle overlapsee,

pressions which are widened at the lower end and which in the lower row extend thus widened to the edge of the shin 1e, and cleats shaped tofit the shingle lodge between the overlapped margins of the shingle atvsuch theirlower ends projecting channels havin beyond the lower edge of. theoverlapping shingle and clenched ack thereonto at the,

anels ineaeh row being separated from eac otherbydea widened lower end of the depressions between the panels.

2. A sheet metal struck up for subdivision in panels separated by intervening depressions, such depressions being widened at the lower edge of each shingle, an annular boss 7 portion for the being formed in the widened purpose set forth.

3. A sheet-metal shingle having lateral marginal V-shaped ribs adapted to besuccessively interlapped, the outerlap rib having cylindrical bosses at intervalsvin the 'len th of such ribs depressed at their upper en s to form gasket-pockets. i

In testimony whereof I have hereunto set: I this 12th day ALBERT FRI-EDLEY,

my hand, at Chicago, Illinois, of June, A. D 1905.
